Hi, i would like to use an FMRI ROI as a label from which to extract some curvature metrics in single subjects. all my FMRI ROIs are in nifti volume format, in the same space as my freesurfer segmentations.

i've tried this tutorial:

https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness?

and it works for cortical thickness, but don't know how to use it to get the other metrics like curvature.

thanks,

Russell?
